Memory Avatar

1. Introduction

The Memory Avatar platform was designed as a secure, encrypted digital space for creating and delivering sensitive thoughts, memories, and personal audio messages.

The system is architected to:

• Ensure maximum data privacy
• Eliminate internal administrator access to user content
• Provide controlled and verified access to recordings
• Enable an automated digital legacy mechanism

Security is not a feature — it is foundational architecture.

2. Data Protection Architecture

2.1 PII Protection

All personally identifiable information (PII) is encrypted at rest, including:

• Email addresses
• First and last names
• Phone numbers
• Metadata

2.2 SSL/TLS Communication

All client-server communication is secured via SSL/TLS encryption, protecting against man-in-the-middle attacks, data interception, and session manipulation.

2.3 KMS Key Management

Encryption keys are managed through AWS Key Management Service (KMS). Keys are not stored at the application layer and are governed by strict access policies.

3. Audio File Encryption Model

3.1 Zero-Access Principle

All audio files are encrypted using unique, individual encryption keys.

• Administrators cannot listen to audio content
• Developers cannot access decrypted files
• No internal reconstruction of key combinations is possible

The system follows a Zero-Access architecture principle.

4. Dual-Key Unlocking Mechanism

4.1 Two-Code Architecture

Each audio file requires two independent codes:

• Code 1 delivered via email
• Code 2 delivered via SMS

Only when both codes are entered correctly is a temporary decryption key generated. If one code is incorrect, the file remains locked permanently.

4.2 Protection Against Incorrect Contact Information

If either the email or phone number is incorrect, the system prevents unintended access. This significantly reduces accidental delivery risk.

5. Limited Playback Model

• Dual verification required
• Maximum 3 playbacks
• Automatic lock after 90 days
• Re-authentication may be required

Content is never permanently exposed in uncontrolled environments.

6. Digital Legacy (Trustees) Mechanism

If a user does not log in for 180 days:

• Trustee verification process begins
• Multi-week confirmation period
• Account activity monitored

If confirmed inactive, all designated recordings are released to recipients, regardless of subscription status.

Digital legacy activation is a core system function.

7. Data Non-Usage Policy

• No data selling
• No advertising usage
• No commercial content analysis

Privacy is enforced through architecture — not merely through legal terms.

8. Conclusion

Memory Avatar is built as:

• An end-to-end encrypted emotional vault
• A dual-verified delivery system
• A limited-access audio communication infrastructure
• An automated digital legacy platform

Technology does not monitor. It protects.
